Even number are 2,4,6,..,100=50
Probability that it's an even number =50/100=1/2
2)Numbers less than 14 are 2,3,4,5,6,7,8,9,10,11,12,13=12
Probability=12/100=3/25
3) Perfect square are=4,9,16,25,36,49,64,81,100=9
Probability=9/100

2nd
favourable : 12
probability = 12/100 = 3/25
3rd
favourable : 10
probability = 10 / 100 = 1/10
4th
